KNIFE FOR CUTTlNG HAY OR CANE.

SPECIFICATION formingpart of Letters Patent, No. 632,287, datedSeptember 5, 1899. Application filed February 20, 1899. Serial No.706,108. (No model.)

To all whom it may concern:

Be it known that I, J UDSON D. SWAOIOK, a citizen of the United States,residing at Canton, in the county of Stark and State of Ohio, haveinvented new and useful Improvements in Knives for Cutting Hay or Oane,of which the following is a specification.

My invention relates to improvements in knives for cutting hay or cane;and it consists of certain novel features of construction and in formingthe shank in such a manner as to provide a seat for the sections formingthe knife-blade, thus reducing the thickness of the knife and at thesame time providing a shoulder or flange against which the sectionsabut, the shoulder terminating short of the end of the shank at an anglecorresponding to the angle of the last section, thus providing a backfor the point-section in a line with the line of resistance, preventingthe breaking of the shank at the end and reducing the knife to a minimumthickness at the point, as will be hereinafter more fully described andclaimed.

In the accompanying drawings similar letters of reference refer tosimilar parts.

Figure 1 is a perspective view of the knife. Fig. 2 is an enlargedperspective view of the end or point of the shank. Fig. 3 is acrosssectional view of the shank, showing the projecting flange and theseat for the knife-sections. Fig. 4 is an'enlarged perspective view ofthe end or point section.

A is the shank, to which may be attached in any desired manner thehandles B and O. I have shown these handles provided with radial ribs attheir point of contact with the shank to engage with correspondingradial ribs; but any desired form of engagement may be used. The shank Aconsists of a piece of forged or cast metal, upon which there is formedat its upper edge aprojecting flange or shoulder a, terminating short ofthe outer end in a projecting angular flange a upon a line parallel tothe outer cutting edge of the pointsection. The extent of the projectionof the flange a is equal to the thickness of the knifesection, and thusforms a plane a to which are riveted the knife-sections.

The cutting edge of the knife is formed of a required number of sectionsD, having formed thereon proper cutting edges, and a tire utility of theknife.

back or point of resistance in line with the cutting edge.

Heretofore in knives of this character the blades have been formed of asingle section, either riveted to a fiat shank, thusincreasing thethickness of the knife and bringing all the resistance upon the rivetsby which the blade was attached to the shank, or the shank has notextended the entire length of the knife, and the knife has been fastenedto the end of the shank near the handles, or when the knife has beenmade of sections they have been riveted to the flat surface of theshank, and the result has been in each instance that the entireresistance has been against the rivets, which has had a tendencytoweaken the shank, which frequently broke, destroying the en- My deviceovercomes all these difficulties, and by means of the new and novelconstruction and arrangement of the projecting flange upon the shank andthe termination thereof in the beveled flange corresponding to thebeveled cutting edge at the point-section I provide an additionalsafeguard against the line of resistance and prevent either the workingloose of the rivets or the breaking of the shank.

In operation and in the contact of the knife with the'hay the projectingflange forms a back for the protection of the knife-sections and a lineof resistance corresponding to the cutting edge and relieves thepressure upon the rivets and prevents them from either working loose orthe breaking of the shank.

Having thus fully described my invention, what I desire to claim andsecure by Letters Patent is 1. The combination in a knife for cuttinghay or cane, of a shank provided with a projecting flange terminating inan acute angle short of the end of the shank, knife-sections riveted tothe shank and abutting the flange, substantially as described and forthe purpose set forth.

2. The combination in a knife for cutting hay or cane, of a shankprovided With a projecting flange terminating in an acute angle short ofthe end of the shank, andin line with the cutting edge of theknife-sections, knifesections riveted to the shank and abutting againstthe flange, substantially as described and for the purpose set forth.

3. A shank for knives for cutting hay or cane, provided with aprojecting flange in line with and parallel to the cutting edges of theknife-blades to be attached thereto, and terminating in an acute angleshort of the end of the shank, substantially as described and for thepurpose set forth.

In testimony whereof I have hereunto set my hand in the presence of twosubscribing witnesses.
